GKC-BA Tester for Mechanical Characteristic of High-voltage Circuit Breaker

GKC-BA Tester for Mechanical Characteristic of High-voltage Circuit Breaker  

Overview

This product applies to the mechanical properties test of all kinds of import or domestic models of bulk-oil circuit breaker, oil-poor circuit breaker, SF6-type, vacuum and other circuit breaker. It is also applicable to time tests of electromagnetic appliances (such as contactors, relays, etc.).

Main properties 

Features

LCD display, Chinese menu, printing device, simple operation;

Comprehensive analysis and display of test data;

Using the data table to show the main parameters of the circuit breaker;

display the test data clearly with travel time curve, travel speed curve, port statechart diagram and time&current curve; show the coordinates of any point on the curve;

Provide an internal power supply: adjustable DC (0-250V), current: less than 15A;

Any external power supply also can be controlled and measured by our instrument.

If the operating machine needs an AC power supply, we can use the AC sampling methods in the test.
